I think that your rose is hungry - there won't be many nutrients in that soil. Although leaves will contribute to the quality of the soil when they have decomposed, the actual process of decompostion can use up a lot of the nitrogen in the soil.
I would have used 50% soil and 50% well rotted farmyard manure.
I suggest that you get some manure from the garden centre and repot your rose in a 50/50 mix of topsoil and manure.
In a couple of months it will be much happier.
